Eccrine spiradenoma is a rare benign adnexal epithelial neoplasm characterized by a bluish-pink, slow-growing solitary nodule, coursing with paroxysmal pain, mainly in young adults. It is most commonly located in the trunk and extremities. Bleeding and/or ulceration are common in the giant vascular variant, which is characterized by a size greater than 2 cm in diameter and a high degree of vascularization seen on histology. Its clinical characteristics are unspecific and require biopsy with histological analysis for diagnosis. Its histology presents one or more basophilic intradermal lobules enveloped in a fibrous capsule without connection to the epidermis. It presents two types of cells: small cells with dark nuclei in the periphery and large cells with light nuclei in the center. An accurate diagnosis is important due to the fact that it can develop into a potentially fatal malignancy - which is a rare phenomenon and occurs most often in the multiple variant. A rare case of eccrine spiradenoma in the abdomen with bleeding associated is described in the present paper, as well as a discussion on possible treatments.

Rhinophyma is characterized by the hyperplasia of sebaceous glands in the nasal region, associated with a nodular thickening of the skin, enlargement of the pores, and fibrosis in the later stages. It occurs most commonly in male patients bearing rosacea, and may be associated with phymas in the region of the mentum (gnatophyma), ears (otophyma) and forehead (metophyma). The present article describes a case of giant rhinophyma with significant impact on the patient's quality of life, hampering breathing, sleeping, and eating. The lesion was successfully treated with electrosurgery.

Introduction: Mohs micrographic surgery is a technique that offers high cure rates for non-melanoma skin cancer.
Objective: To describe the clinical and epidemiological profile of patients who underwent Mohs micrographic surgery in a reference center in dermatologic surgery.
Methods: Medical records of patients who underwent Mohs micrographic surgery in the period 2014-2015 at a dermatology reference center, in the city of Mogi das Cruzes (SP, Brazil), were analyzed.
Results: The patients' ages ranged from 38 to 87 years; of these 54% were women. The most affected topography was the nose (54% of patients). Previous history of skin cancer was positive in 62% of cases. The indication driver for micrographic surgery was the lesion's location in 67% of the patients, followed by the size (23%) and tumor recurrence (10%). The most prevalent intraoperative diagnosis was basal cell carcinoma (90%).
Conclusions: Mohs micrographic surgery is an excellent therapeutic option in cases of tumors of aggressive nature, large diameter and high-risk location. This study is in line with the current literature regarding the epidemiological data linked to the occurrence of nonmelanoma skin cancer.

Introduction: Hyperhidrosis is a common disease characterized by excessive sweating. Several treatment options are described as axillary liposuction and laserlipolysis.
Objective: To compare the effectiveness of two treatment methods for axillary hyperhidrosis – one exclusively surgical (liposuction) and the other employing invasive laser therapy (laserlipolysis) – using a prospective, comparative study with a one-year follow up.
Methods: Liposuction was carried out in the right axilla, while laser lipolysis was performed in the left axilla. The evaluation was conducted using the starch-iodine test, comparative histological analysis and patient self-assessment questionnaires.
Results: Twelve patients took part in the study. The starch-iodine test indicated decreased sweating in all patients within one year after the procedures, while the histological analyses showed absence or reduction of the secreting ducts and acini on both sides and in all cases. After one year of follow-up, the patient's satisfaction index measured by the questionnaires remained positive in all cases, with 75% asserting maximum satisfaction, and 25% reporting difference between the sides (better results were described in the right hand side axilla).
Conclusions: Both techniques showed similar effectiveness after one year of follow-up. Laserlipolysis had a lower frequency of postoperative complications.

Hidradenitis suppurativa is a chronic inflammatory, recurrent and debilitating skin disease. Its etiopathogenesis involves follicular occlusion and genetic, environmental and immunological factors. Diagnosis is predominantly clinical, and the therapeutic approach is a major challenge due to its impact on the patient's quality of life. The surgical option is the most indicated in severe cases, nevertheless there is no consensus on the ideal treatment, as outcomes are diverse, and the aesthetic aspect after the procedure is generally unfavorable. This article was aimed at reporting a surgical option with primary wound closure, whose aesthetic result was superior to those derived from traditional techniques.

Introduction: Molluscum contagiosum is a dermatovirosis caused by a poxvirus. In the literature there are descriptions of different therapeutic approaches of this infection.
Objective: To evaluate the efficacy of imiquimod – isolated and associated with curettage – in the treatment of molluscum contagiosum.
Methods: Group A: 20 patients used 5% imiquimod cream 3 times a week for 6 weeks. Group B: 10 patients used a creamy base 3 times a week, for 6 weeks. After the initial 6 weeks, all patients underwent curettage.
Results: Group A: 31% decrease in the number of lesions in the 6th week, with a curettage effectiveness of 97.6%; Group B: 4.8% increase in the number of lesions in the 6th week, with a curettage effectiveness of 81.1%. The mean value for the pain level during curettage was 1.8 for Group A and 3.0 for Group B.
Conclusions: Due to the facts that the rate of cure of contagious molluscum lesions increased and the pain decreased when the curettage procedure was conducted after the use of the immunomodulator, it was possible to conclude that the association of 5% imiquimod cream to the curettage may be a therapeutic possibility.

Among the diverse reconstruction alternatives used in surgical wounds, those employing cutaneous grafts are implemented when the closure – primary or by second intention – is unfeasible or, due to other factors, flaps are not recommend. The repair of surgical wounds using partial thickness graft obtained from the scalp with a flexible blade is described in 3 cases of conventional exeresis (2 basal cell carcinomas in the nasal region and 1 case of squamous cell carcinoma on the dorsum of the hand). The technique yielded good aesthetic outcomes, both in the receiver and donor areas.

Skin cancers in the head and neck region account for 70-75% of malignant cutaneous tumors, of which 80% are basal cell carcinomas. Between 3-6% of malignant cutaneous tumors occur in the auricular pavilion. The authors of the present paper report an alternative technique for reconstructing the ear helix after excision of tumors, without the use of the classic compensation triangle. This method allows that the scar be located in the helical sulcus, resulting in a better aesthetic result, without unaesthetic retractions or scars located transversely to the helix.

Non-melanoma skin cancer is the most common neoplasia in humans, and basal cell carcinomas (BCC) account for approximately 80% of cases. Cumulative exposure to ultraviolet radiation (UV) is the main risk factor associated to BCC, with a higher incidence in photoexposed areas, including the auricular region. The auricular region is a noble cosmetic unit, with anatomical peculiarities that lead surgeries to require the excision of a large amount of tissue, presenting a challenge for the dermatological surgeon. The authors present a case of helix reconstruction with a triple transposition flap.

Brooke-Spiegler syndrome is a rare autosomal dominant genetic disease with predisposition to many adnexal tumors, including trichoepithelioma, cylindroma and spiroadenoma. Tumors appear in the second decade of life, progressively increase with age, and their prevalence is higher in women. It is caused by a mutation in the CYLD gene, localized in the chromosome 16q12-q13. We report a exuberant case of giant eccrine spiradenoma associated to this syndrome.

Rhinophyma is a disfiguring and progressive disease of the nose with high prevalence. Despite being considered a benign condition, many patients have sought curative treatments due to aesthetic deformity and social stigmatization. There are several surgical techniques described in the treatment of this disease. This report aims to present a case that required an unusual therapeutic approach for the treatment of rhinophyma, given the patient's multiple comorbidities. The procedure was performed with no complications in the intra and postoperative period. The patient maintains an outpatient follow-up with a good long-term aesthetic result.

The lower eyelid is one of the sites most affected by basal cell carcinoma (BCC). We present an option of inner corner skin flap with oral mucosa graft for eyelid reconstruction after BCC excision. This tumor affects approximately 60% of the lower eyelid and shows complete lower lacrimal canaliculus involvement. The use of internal corner skin transposition flap and oral mucosa graft is safe. The technique is reproducible and with good postoperative evolution. Positioning and eyelid movement were restored, allowing tear drainage through the upper canaliculus with complete correction of the tears’ overflow (epiphora).

O queratoacantoma (QA), apesar de frequente na prática diária, é um tumor que gera questionamentos. O aspecto mais intrigante associa-se à sua posição no limite entre malignidade e benignidade. A abordagem do tumor, bem como sua classificação, é controversa. Na definição da conduta, é importante levar em conta o potencial de transformação para carcinoma espinocelular. Desse modo, a excisão cirúrgica é a terapia de escolha, sempre que possível. Algumas situações merecem atenção adicional, como a imunossupressão associada. Neste artigo, relatamos um caso de QA gigante em um paciente com síndrome da imunodeficiência adquirida tratado com cirurgia micrográfica de Mohs.

O fibroxantoma atípico (FXA) é um tumor mesenquimal raro que geralmente acomete pacientes com idade avançada, do sexo masculino, em áreas fotoexpostas. É mais frequente na cabeça e pescoço, mas também pode ocorrer no tronco e nas extremidades. Atualmente, é considerado um tumor benigno de diagnóstico por exclusão, com baixa taxa de recidiva e metástase. O tratamento é realizado com excisão cirúrgica, o que permite o diagnóstico por avaliação histológica e imuno-histoquímica.
